So there's this guy, we've been friends for a couple months now, and people always thinks he likes me. but lately he's been different in math class. Not necessarily really mean, put not nice. But when he sits next to me on the bus, he's really chill and nice. He's even told me about some difficult situations in his family life that he wouldn't just tell anybody. I'm just confused, I don't understand how you can go from being normal in class to being weird and I guess you can say mean. but its nothing to get offended by.
